Never had a problem with the car. Took it in to the dealer for a timing chain tensioner recall and now my timing chain or the tensioners have failed and the car will not start.

The contact owns a 2007 Cadillac Cts. The contact stated that the engine exploded. The contact was driving 78 mph when the cruise control inadvertently disengaged. A loud booming noise emitted from the engine while a flash of fire and smoke emitted from the rear exhaust. Smoke then began to rise from the engine. The contact also stated that a rattling chain sound also began to come from the engine. There were no warnings prior to the failure. The vehicle was taken to the dealer, but the dealer was unable to inspect the vehicle. The dealer informed the contact that this was a known failure. The failure and current mileages were 38,991.

Engine light on dashboard warned that there was a problem. After investigation it was clear that the timing chain had to be replaced. This was carried out without any courtesy from import-organization or dealer. After 28,000 miles? unbelievable. It cost me a lot of money.

I purchased a used 2007 Cadillac Cts in November 2009. From that time, it always hesitates with the first forward acceleration of the morning, and then has a forceful acceleration as it overcomes the hesitation/almost stalling, and then drives normally. As this was a new car for me, I thought that maybe the car needed to warm up due to the cold weather over winter. Once the temperatures increased, the car continued to experience the problem - daily. The car is at the dealer again - 5th visit since March 2010. The first visit they found nothing, the second visit found a worn timing belt, third visit found nothing, fourth visit took 5 days and found connectivity errors with the drive-wire system. There was an erratic signal from tac module; replaced terminals circuit # 581 & #582 (throttle actuator). The repairs did not fix the issue and I took the car back after 3 days for the 5th visit. The dealer has indicated that they have replicated the problem, but do not know how to solve it. This complaint has been escalated up to the district-level support and I am now waiting for GM to send an engineer to the dealership to try to figure out how to solve the problem. It is frightening to drive a car that repeatedly wants to stall and then over-accelerates to overcome the problem causing the hesitation. It is also frightening that it is taking 5 visits for the dealer to recognize the serious nature of this problem, with no solution in sight. It is unsafe to drive a car that randomly tries to stall, and then overcompensates by a strong/forceful acceleration.

February 2008, . received recall letter for new Cadillac 2007. Appointment was made and problem has not been corrected - end of February 2008. Car still leaks from engine and leaves residue in driveway where parked. Contacted dealership and they are not interested in repairing. Cadillac customer service made another appointment for diagnostic for May 2008. Car still not corrected. Feel the car should be replaced. Bought brand new - am 80 years old and need vehicle that is safe and secure. Main reason for purchase. I cannot continue to take car back and forth to dealership and problem not corrected. Feel it is a tactic and car should be replaced. The recall drive axle differential seal - bearings and other components including drive wheels, brakes, engine, etc.....
